CCD7 — Solanum lycopersicum

Summary

SlCCD7 (SOLYC01G090660.3) on tomato chromosome 1 encodes a carotenoid oxygenase family protein with 9-cis-beta-carotene 9',10'-cleavage oxygenase activity, localised to the chloroplast stroma and plastid. The gene is associated with strigolactone anabolism, carotenoid and apocarotenoid metabolism, and hormone metabolism, and has been linked to shoot branching, axillary branching, lateral root development, root system architecture, plant height, leaf senescence, flowering time, and seed dormancy. Associations also include response to water, salt response, response to nitrogen deficiency, and drought tolerance, as well as traits such as photosynthetic rate, stomatal resistance, carotenoid and anthocyanin content, plant dry weight, and sugar and amino acid content. Studies of related genes in other species link the family to strigolactone biosynthesis, lateral branching, vascular tissue development, and cold stress tolerance.
